Hi, I've been looking at a 500cc bike for sale that is fitted with a restrictor. It also comes with the parts to de-restrict it. Firstly, why are bikes like this restricted? And is it difficult to put it back to full power?

thanks

Firstly, so that the rider can comply with any restriction applicable to his/her licence.


And yes, usually.

once upon a time bikes were often restricted to 33bhp to allow them to be ridden by riders aged 17-21, however the EU got involved and now it's a lot more complicated.. now there is like 3 or 4 different kinds of licence for various sizes and power ranges.


I don't know about your bike specifically but often there was a simple mechanical restriction at the carb/throttle body, simply obstructing the young rider from opening up the taps to full potential and limiting the power outputs.


check exactly how the bike in question is restricted but as above. Yes, they're usually quite simply put back to standard.

My XJ6 was restricted to 33bhp until my licence de restricted. It handled the restriction fine l, a little hesitant in 4th at 4k. Since having the restrictor out the bike it back to full power and its like nothing has happend.


I wouldnt worry about it.
